It is the agenda of The Revival that has given us Folk Music, not the so-called source singers who merely provided them with the sort of songs they were interested in. We might think of this bias as an unnatural sort of selection and lament that the broader cultural context of Traditional Song has been all but lost to us. Did anyone, for example, think to collect more popular / music hall / parlour songs from the repertoires of the old singers and determine to what extent that they too had been effected by the folk process?
